3 3 Editorial Smart Intelligence How much energy am I consuming? When am I consuming energy? How do I pay for energy? If you do not have an answer to these questions, you are not controlling your energy consumption. The solution lies in metering. Actually, you can achieve potential savings if you are capable of managing and optimising the amount of energy you consume. To this end, metering is vital, with the purpose of detecting potential savings, immediately warning you about anomalous consumption and simplifying the electric energy management procedures of your installation. Effective management starts with having a clear view of what energy is consumed and when it is consumed, in order to take decisions on contracting power services. The basic principles of energy intelligence involve gathering, classifying and transforming energy data in structured form for its subsequent analysis, after which decisions can be taken. The energy intelligence concept is a key factor for the competitiveness of a company and is one of the lines being followed by the different global energy efficiency programmes. For Europe, Directive 2012/27/EU requires large companies to implement an energy management system (ISO 50001) before 5 December, The energy intelligence concept is reaffirmed in Lord Kelvin's famous quote "If you cannot measure it, you cannot improve it.» Francesc Fornieles Market Development Manager Marketing Dept. of CIRCUTOR SA

4 4 Products Jonathan Azañón Energy Management Division You have the power An efficiency expert always with you In the current era of information, energy consumers must be able to obtain data on their electrical consumption, in order to be able to take action to improve the energy efficiency of their installations and to make substantial savings in their electricity bill. Likewise, due to the difficulty of obtaining consumption data from the installed electronic meters, users do not have the chance to react before receiving their electricity bill. To help us therefore understand how we consume energy and how to reduce consumption, CIRCUTOR is launching one of the most innovative products on the market in recent years: Wibeee. Cable-free. Wireless system The entire system has been designed to monitor information over wireless communications networks. Nothing can come between Wibeee and you.

11 11 Technical article Jonathan Azañon Electric Energy Management and Network Quality Division CVM-NET4+ Complies with the Energy Efficiency standards New multi-channel consumption and power analyzer Current situation The current market standards establish the guidelines for the implementation of new systems that can manage consumption data, with the purpose of knowing how and when our installations are consuming energy. The new European Directive 27/2012 EU will come into force during 2015, establishing a national objective for improving the efficiency of large companies. This obliges installation managers to have verifiable and quantifiable data about the different energy uses of their installations. This information will be vital for achieving a better understanding of how each installation behaves and for controlling such behaviour, since one of the key objectives is to achieve a 20% reduction in the energy consumption of these installations. These companies are obliged to perform external audits to corroborate the compliance of their systems with the new standards. Therefore, these companies have the option to install their own Energy Management System (EMS) as an alternative to performing an external audit. In addition, some standards, such as ISO 50001, also applicable to SMEs, already recommend these types of systems with the purpose of measuring and quantifying the consumption of energy per zone and type of use, which are useful for the continuous improvement of different energy processes and systems. When addressing how the system must be installed, the features of electrical installations are not always constant, i.e., many different single-phase channels often exist in switchboards. To this end, units that can measure different types of lines in a reduced space must be installed, avoiding the installation of new measurement sub-panels. This is quite a critical point, since significant investment will be required to adapt the measurement system if the consumption analyzers cannot be installed in existing panels.

12 12 Solution The new CVM-NET4+ multi-channel power analyzer has been specially designed for multi-channel applications in existing panels, providing information on over 750 electrical variables for the complete management of installations.

This tool is called PowerStudio Scada and it covers all the necessary options for analysing the data gathered and taking decisions to make your installations energy efficient. Efficient three-phase measurement transformers, specially designed for modular electric panels The MC measurement system offers significant advantages to professionals during the power analyzer and meter implementation and installation phase in electric panels. The MC3 system is composed of three efficient transformers in a compact arrangement; its dimensions make it a simple and innovating system for 63A, 125A and 250A panels. The MC1 system allows line extensions in electric panels, by simply changing the transformer secondary, as it is a compact multi-range system.

17 Circutor Magazine Application CIRCUTOR's headquarters are located in Viladecavalls (Barcelona) and they are a good example of the implementation of an Energy Management System (EMS). We can classify the different types of consumption by zone and type of use thanks to the measurements taken by units such as the CVM-NET4+. Therefore, the task of classifying the types of consumption is relatively simple, always taking into account where, how and when electrical energy is consumed, helping take decisions associated with the improvement of electrical energy efficiency. The installation is controlled with PowerStudio Scada energy management software, which can monitor data, produce graphics, tables, Scada screens, reports and alarms, recording all parameters in a database to guarantee system traceability. In addition, another good example of where the application is used are the data processing centres (DPCs) in which the PUE (Power Usage Effectiveness) is calculated as a variable that measures the efficiency of data centres. To do so, the three-phase load measurements, such as the input power of the server room, UPS and air conditioning system power, must be combined with the single-phase loads, such as the consumption of the servers at the UPS output. Therefore, data associated with the PUE and UPS losses is gathered, i.e., data on the efficiency of the system.» PUE Efficiency Calculation Scale: VERY INEFFICIENT START PUE: Power Usage Effectiveness, calculated with the formula: Total energy supplied PUE = Energy for computer equipment END VERY EFFICIENT EMS Energy management system Energy Management System (EMS).

22 22 Pablo de Olavide University PROJECT Certification of the Installation and Energy Efficiency Management System of the UPO, managed with PowerStudio and certified according to the UNE-EN ISO Standard. SECTOR Public Universities CLIENT (UPO) Pablo de Olavide University, Seville Information of interest Energy Management at the installations of the UPO Most significant results SAVINGS 200,000 per year INVESTMENT 150,000 per year PAYBACK PERIOD 5 years Partners / Acknowledgements Thanks to the agreement signed between the UPO and CIRCUTOR, we shall keep the measurement and control elements of the installations of the UPO up-to-date at all times, ensuring that the latest versions of the PowerStudio application are installed. Success story Initial situation Energy demand management is starting to become a vital element of the energy policies of organisations and, in particular, of Spanish universities. The reduction of energy demand is a very economical way of achieving the objectives of reducing the costs of energy supply, minimising the environmental impacts and increasing energy safety. Taking these premises into account, since the foundation of the Pablo de Olavide University (UPO) in Seville in 1997, the Infrastructures, Maintenance and Energy Efficiency area (IMEE) and Computing and Communications Centre (CIC), led by the administration of the UPO, have been increasingly concerned about establishing quality Energy Efficiency management mechanisms for the installations and buildings of the campus, as well as raising awareness on shortages in the availability of energy and its environmental impact, with the participation of the whole university community in achieving these objectives. In turn, the infrastructures of the University have grown from (buildings and installations used for teaching, research and administrative management), which require the efficient management of the matters described in these good practices (management of light, drinking and irrigation water and air conditioning systems, attendance control systems, fire alarms, fire extinguishing systems, surveillance systems, etc.). Objectives The main objective is to optimise the consumption of energy of the installations of the UPO, based on: Raising awareness on the availability of energy and its environmental impact. Improving the use of electrical energy and energy obtained from other sources. Reducing, controlling and structuring internal consumption. Monitoring and controlling electrical energy and drinking water billing. Preventing the costs of using energy, including the corresponding estimates in the annual budgets of the UPO. To achieve these objectives, the Pablo de Olavide University is currently operating an Installation and Energy Efficiency Management System (SGIEE), certified by Bureau Veritas in June 2015, in compliance with the requirements of the ISO 50001:2011 Standard for the activities described in the following scope: The Installation and Energy Efficiency Management System covers the Management of the campus installations of the Pablo de Olavide University in Seville, which are used for Teaching, Research and Administrative Management. This initiative is part of the Strategic Plan, which specifically includes the University's objective to become a leader in the preparation and implementation of ecological preservation policies and programmes, such as energy conservation and saving, with the purpose of creating a biodiverse campus of international renown, as well as implementing energy efficiency and saving policies and fostering the use of renewable energies in the campus.

Log in with user/password: anónimo/anónimo. More information at With an ongoing investment of 150,000 euros per year, the aim is to improve infrastructures and installations, with the purpose of achieving the required levels of reliability, availability, zero interruptions and safety, with a 5-year payback period. This has resulted in savings of approximately 200,000 euros per year, which are invested to improve the installations.

23 Main consumption control Circutor Magazine Power Studio Building 1 Building 2 Irrigation systems 1 Building N Details of the Solution The "PowerStudio" application, i.e., the "germ" of the SGIEE, was implemented as a result of the collaboration with "CIRCUTOR, which supplied the units to be installed and the management software, as well as the contributions and experience in designing the infrastructures, maintenance and energy efficiency area of the UPO. The installation management software is of the open type and manages the communications with the analyzers and system peripherals, so that it can be adapted to the needs of each installation. In 2005, the SGIEE was powerful enough to achieve the current results, with the change in technologies of PowerStudio for the SGIEE, based on a multi-user Web application, as well as the changes associated with the improvement of communication technologies (Communications network of the UPO expanded to 10 GB). The serial converters that were initially installed were replaced with units that use IP technology. This allowed us to excel in field element control. Over the period, we have worked on the requirements of the UNE-EN ISO Standard, with the purpose of implementing them in our SGIEE (Policies, Objectives and Goals, Action Plan, Energy performance indicators, processes and procedures, documentation and log management and control, training and awareness, internal audits and management reviews, improvement plans). Results An energy audit of the UPO was performed in The audit information was used to establish the Baseline of the reference measurements. The Baseline is currently in the re-definition phase.
